Obtain the token information of ordinary users (Xxx.java)

	String serverUrl = "http://localhost:8090/";
    String realm = "realm-01";
    String clientId = "web-client";
    String clientSecret = "8MwGl8X9DfMkk0mmzTaGyZIuMWPIBfjc";
    String username = "user-001";
    String password = "1234";

    Keycloak keycloak = KeycloakBuilder.builder()
            .serverUrl(serverUrl)
            .realm(realm)
            .clientId(clientId)
            .clientSecret(clientSecret)
            .username(username)
            .password(password)
            .grantType(OAuth2Constants.PASSWORD)
            .scope(OAuth2Constants.SCOPE_OPENID)
            .build();

    AccessTokenResponse tokenResponse = keycloak.tokenManager().getAccessToken();
    String accessToken = tokenResponse.getToken();
    String idToken = tokenResponse.getIdToken();
    String refreshToken = tokenResponse.getRefreshToken();
    
    // Get user resource
    RealmResource realmResource = keycloak.realm(realm);
    UserResource userResource = realmResource.users().get("5962a29c-9a13-483e-9ad3-f2a57dbde9a9");

    // Get user representation
    UserRepresentation user = userResource.toRepresentation();

    // Print user information
    System.out.println("User ID: " + user.getId());
    System.out.println("Username: " + user.getUsername());
    System.out.println("Email: " + user.getEmail());

Obtaining higher-level permissions of Keycloak can control some advanced behaviors of Keycloak, such as clearing cache (Xxx.java)

	String serverUrl = "http://localhost:8090/";
    String adminUsername = "admin";
    String adminPassword = "admin";

    Keycloak keycloak = KeycloakBuilder.builder()
            .serverUrl(serverUrl)
            .username(adminUsername)
            .password(adminPassword)
            // 使用 master realm
            .realm("master")
            // 使用内置的 admin-cli 客户端
            .clientId("admin-cli")
            .grantType(OAuth2Constants.PASSWORD)
            .scope(OAuth2Constants.SCOPE_OPENID)
            .build();
	// 清除域下的用户缓存
    keycloak.realm("realm-01").clearUserCache();
